Patent DE-2440577-A1 (DE)
Title: Storage and inspection unit for drawings etc. - comprises displaceable parallelogram frame with loose mounted transverse drawing holders
IPC: A47F7/00
Filed: 1974-08-23
Abstract: The storage/inspection apparatus for large technical drawings and charts etc., comprises a horizontally mounted frame (1) consisting of four parts (2, 4, 6, etc) connected together for articulated movement so as to fold up in the manner of a parallelogram. The drawings (20) are suspended from separate holders or support elements (18) which at their ends rest loosely on opposite frame members (2, 4) so that the drawings can be brought into the field of vision by displacing and/or rotating the frame (1). Since this frame can be displaced by almost (180 deg.) the reverse sides of the drawings can be viewed with minimum effort which is particularly advantageous where large drawings have been folded up. The frame is preferably designed with two longer opposite sides which lie parallel to the wall mounting and with two shorter sides which are approximately the width of the drawings and holders.

Title: Speed or travel measurement of rail vehicles - using accompanying doppler radar directed to track
Inventor: MUELLER KARL HEINZ
IPC: G01S13/60
Filed: 1975-02-17
Abstract: The aerial of the accompanying Doppler radar system is directed diagonally towards the rail track and aligned to the fixing means which fix the rails to the sleepers or the gravel of the track. The fixing means consist of, for example, rail bolts, heads of screw bolts for clamping plates which hold the rail, fishplates or similar parts which feature surfaces vertical to the direction of travel.

Patent DE-2527785-A1 (DE)
Title: Oxygen refining of steel - monitored by changes of sound during refining
Inventor: CLAES JACQUES REGINALS
IPC: C21C5/30
Filed: 1975-06-21
Abstract: In a method for oxygen refining of steel, in which a jet with two concentric nozzles is placed under the surface of the molten metal in an oxygen converter, through the central nozzle of which jet passes oxygen and through the outer nozzle of which passes an endothermic liquid hydrocarbon which serves to protect the refractory surface of the jet, the oxygen input to the converter is controlled to produce steel with the desired low P content. A constant rate of O2 input which is dependent on the Si content of the metal is fed into the converter. When the CO content of the gas from the converter falls suddenly, the O2 input is raised to the maximum possible. The level of sound from the converter will subsequently drop; at this time, the iron content of the slag is measured. From this value, the quantity of O2 required to refine the steel to the desired P content may be determined from a graph. This quantity of oxygen is fed into the converter at maximum rate, and teh steel is then reduced in P content to the desirable level. The advantage of this method is that residual P contents are more consistent than with methods derived from mathematical models.

Title: Level luffing crane control - has hoist rope speed varied dependent on derricking rope speed and jib angle
Inventor: TAX HANS
IPC: B66C23/12
Filed: 1976-05-12
Abstract: The level-luffing crane has a jib derricked by rope, and when derricking the hoist rope speed is so controlled as to keep the path followed by the crane hook horizontal. The speed (Vh) of the hoist rope (9) is' varied by a control unit for the hoist winch (7) in proportion to a desired-value signal fed to it. An emitter supplies a signal proportional to the speed (Vv) of the derricking rope (21), and this signal is modulated in a computer by a predetermined factor dependent on the jib angle, in order to generate the desired-value signal. The factor is a function of the jib angle (5) such as to give level-luffing.

Title: Control circuit for brushless DC motor - incorporates resistance network for adjusting conducting angle and commutation without overlap
Inventor: ROGGE JOACHIM DR ING
IPC: H02P6/14
Filed: 1976-06-30
Abstract: The control signals are obtained from the auxiliary windings (51, 52, 53), in which permanent magnets on the rotor induce a voltage. These voltages are applied to pairs of resistors connected in a ring. The centre point of each pair forms one input of an amplifier, the other being a reference voltage. The amplifiers control the switching transistors. If the mid point voltage exceeds the reference the associated transistor turns on and current flows in the main winding not associated in phase with the summed voltage in the resistor pair. If the voltage of the next auxiliary winding falls below that of the sum conduction is maintained, but if it falls below the reference conduction ceases.
